Bill Blair, a saxophone player at the Club Bolero, is in love with socialite Patricia Lawson, even though he has never met her. On the day of her wedding to T. Ames Pierpont III, Bill and his pal, Barney Keenan, crash the wedding by tricking one of the invited guests to enter through a side entrance, then taking his invitation for themselves. During the wedding ceremony, when the minister asks if anyone objects, Bill jumps up and says that he does because he loves her. He is quickly taken to another room where Pat's father, advertising agency owner John Hodge Lawson, gives Bill a stern lecture. The ceremony then starts over, but this time Pat objects and runs into the garden. There she sees Bill and tells him that the wedding was not her idea, but something her father arranged as a business deal. While talking, Pat realizes that she has fallen in love with the fun-loving Bill and proposes to him. They then decide to take her honeymoon tickets to Europe and promise always to have fun together. After the honeymoon, however, things begin to change. Within two years, Bill, who has been given a job in Lawson's agency, becomes a dedicated businessman, more interested in making money than having fun. On their second anniversary, Bill forgets about their party and instead goes to a nightclub with Mr. Lawson, Barney and nightclub singer Flo Heath. When he returns to the apartment drunk, Pat is furious. The next night, after a day of arguing with Pat, Bill goes with her father to the Club Bolero to see Flo sing, while Pat goes out with a friend, Mark Shelby. They also go to the Club Bolero and wind up sharing a table with Bill and Pat's father. When a drunken Flo joins the table and off-handedly mentions that she saw Bill in Chicago when he was on a business trip, Pat goes home, leaving a note to Bill saying that they aren't having fun anymore. Angered at Pat, Bill decides to serve her with divorce papers, then takes a saxophone job with Barney on a ship to Europe. Pat, meanwhile, decides to go to Paris and get a French divorce before Bill can divorce her. By terms of French law, before a divorce can be granted, both parties must meet one last time to discuss their differences, and when Bill arrives, he is shocked at the charges in Pat's divorce petition. She says that her lawyers made her include things to get the divorce through without problems, but Bill insists that she accompany him that evening and bring a photographer along to prove that he really is guilty of her charges of debauchery. As they go from night spot to night spot that night, Pat becomes increasingly amused as Bill crosses each of the charges off a list until no more are left. The next morning, Bill shows his picture in the papers and the judge is about to pronounce them divorced when Pat says she objects. She then runs out of the courtroom, followed by Bill. When he catches her she says "Are we having fun yet?" and he says "You bet we are!"
